Soon, very soon, Thursday, February 11, at 10:30 Eastern time, we are likely to learn at any one of several press conferences – at the National Press Club in Washington, D.C., in Hannover, Germany, near Pisa in Italy and elswhere – that gravitational waves have been measured directly, for the first time. This would mean the first direct detection of minute distortions of...

New Delhi: Originally predicted in the early 20th century by Albert Einstein, gravitational waves – ripples in space and time – were not detected until 2015, when the Laser Interferometer Gravitational-wave Observatory (LIGO) identified the first such signal from two merging black holes. On Wednesday, scientists announced the detection of a fourth gravitational wave signal...

Why is gravitational wave suddenly being reported in so many mainstream media lately (late 2016-2017) even though it is not a new topic of discussion in the scientific community? As it turned out, it is due to the fact that three U.S. physicists (Rainer Weiss, Barry Barish, and Kip Thorne) Rainer Weiss (Attribution: Das at the English language Wikipedia, presented at...

Prof. Sanjeev Dhurandhar at IUCAA during the announcement of detection of gravitational waves. (Express Photo) Three decades before international scientists announced they have detected the gravitational waves Albert Einstein had proposed, a young scientist was already talking about the idea. Sanjeev Dhurandhar’s ideas were then greeted with incredulity but, on Thursday, he was...

It's official: this Thursday, February 11, at 10:30 EST, there will be parallel press conferences at the National Press Club in Washington, D.C., in Hannover, Germany, and near Pisa in Italy. Not officially confirmed, but highly probable, is that people running the LIGO gravitational wave detectors will announce the first direct detection of a gravitational wave. The first...

The Absurdity of Detecting Gravitational Waves

The Absurdity of Detecting Gravitational Waves

A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible.
When scientists want one megawatt of laser power, it\'s not just for fun (though I\'m sure it\'s that too), it\'s because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you\'re trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won\'t do.

Today, over 100 years after Einstein proposed his theory of general relativity, we are proud to announce that his final major prediction has been verified! Gravitational waves have officially been detected by LIGO! We are still getting details as the teams of physicists go over the data, but this is a huge deal, and is an exciting new step in understanding our universe.

Neutron Star Merger Gravitational Waves and Gamma Rays

Neutron Star Merger Gravitational Waves and Gamma Rays

The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates:
- the first gravitational waves detected from inspiraling neutron stars
- the first joint observation by gravitational wave and electromagnetic wave astronomy
- identification of a gamma ray burst in conjunction with merging neutron stars
- how gravitational waves and gamma rays can be used together to locate their source
All evidence so far indicates that the data support General Relativity.

Gravitational waves offer a remarkable opportunity to see the universe from a new perspective, providing access to astrophysical insights that are available in no other way. The Initial LIGO gravitational wave detectors completed observations at and beyond their original design sensitivity in 2007,

Astronomy based on gravitational waves has been primarily done by the Laser Interferometer Gravitational Wave Observatory, known as LIGO. But recently, VIRGO, ran by the European Gravitational Observatory, was turned on to operational data gathering, and the first jointly detected gravitational wave
